Print head for an additive manufacturing system, and additive manufacturing system

Abstract

The present disclosure relates to a print head for an additive manufacturing system, in particular for a 3D printer, comprising at least one temperature control element, in particular a cooling element, which is arranged adjacent to the print head.The present disclosure further relates to an additive manufacturing system, in particular a 3D printer, comprising at least one print head.

The invention claimed is: 
     
       1. A print head for an additive manufacturing system, the print head comprising a compressed air source, a pressure reducer, and at least one temperature control element, the at least one temperature control element of the print head includes a ring nozzle arranged adjacent to a print material deposition device of the print head, the at least one temperature control element comprising at least one flow heater, wherein the compressed air source is configured to provide compressed air to the at least one flow heater via the pressure reducer, and wherein the compressed air is heated at the at least one flow heater and flowed to the ring nozzle,
 wherein the at least one temperature control element comprises at least one controllable valve positioned downstream of the at least one flow heater and upstream of the print material deposition device, wherein the at least one controllable valve is constituted such that the at least one controllable valve adjusts air mass flow therethrough to the ring nozzle of the at least one temperature control element, the ring nozzle surrounding the print material deposition device of the print head, 
 wherein the at least one controllable valve is positioned in a build-up chamber, 
 wherein the at least one controllable valve is configured to guide air to the ring nozzle or into the build-up chamber, and 
 wherein the at least one controllable valve is configured to provide an adjustment in a range, wherein a first end of the range comprises all of the air being directed completely into the build-up chamber, and wherein a second end of the range comprises all of the air being directed completely onto a component being manufactured by the additive manufacturing system. 
 
     
     
       2. The print head according to  claim 1 , wherein the at least one temperature control element is or comprises at least one fluid supply. 
     
     
       3. The print head according to  claim 2 , wherein the at least one fluid supply is a cooling air supply. 
     
     
       4. The print head according to  claim 1 , wherein the at least one temperature control element is or comprises at least one nozzle. 
     
     
       5. The print head according to  claim 1 , wherein the at least one temperature control element is in a fixed position. 
     
     
       6. The print head according to  claim 1 , wherein the at least one temperature control element comprises at least one fluid source. 
     
     
       7. The print head according to  claim 1 , wherein the additive manufacturing system is for a 3D printer. 
     
     
       8. The print head according to  claim 1 , wherein the at least one temperature control element is a cooling element. 
     
     
       9. The print head according to  claim 1 , wherein there is a continuous air flow through the at least one flow heater. 
     
     
       10. The print head according to  claim 1 , wherein the first end of the range is 0 l/min, and wherein the second end of the range is 20 l/min. 
     
     
       11. An additive manufacturing system, comprising at least one print head according to  claim 1 .
